My opinion depends more on classes because some expansions tier sets were either fucked up or godly looking. But as an overall statement, TBC no doubt and next to it vanilla. I loved pala t2 and warrior t2 along with other t2 sets

I'm really partial to T6... My priests 8/8 T6 is among my most prized possessions. Priest's T5 is quite good too and has aged better than most, and their Tier 4 was really great too. Warlock Season 2 is my favorite PvP set of all time, and Paladin Season 2 gets an honorable mention. BC also has tons and tons of off-set items worthy of x-mog, especially weapons, not to mention those iconic warglaives.

Wrath would come in 2nd easily. MoP sets all around are very good, high quality sets but in comparison to BC or WotLK I hate to say they come across as uninspired to me. The Rogue Tyrannical set makes me look like Shredder and when I saw it I knew I had to have it, but other than that I haven't seen any sets that have come across as visually distinctive enough to leave a real impact on me the way that say the Season 2 Paladin set did once. Ironically one of the few pieces to have that kind of flair in my view is the Replica Shado-Pan Helmet, a transmog-only piece.

Only good set personally in MoP is the sha infused clothing for warlock that's fucking amazing.

That's the set my warlock is rocking, it's beast. But I just ifnd all the other MoP sets to be..sooo...green? Like they remind me of green armor sets not epic this is the last raid of the expansion sets. lol

TBC indeed. Some classes had three tiers of awesome, every class had at least one great looking tier. That's not counting the Sunwell gear at all (and I think the hunter color for mail and all the cloth ones looked awesome).

I liked all tier sets for shamans. I can't really say which expansion had the best. I didn't really raid during Cata and I think I am kinda biased because I was far more attached to the tier sets during TBC for obvious reasons (more 'exclusive'/rare).

I have to say the T6 set for warriors is still my favorite combined with Bulwark of Azzinoth but I am also a big fan of shaman T5 and dualwielding Claw of Molten Fury and Fist of Molten Fury and shaman T6.

Shaman T6 is also spacey but I liked it a lot more than shaman T10 which was some nature shit in an undead raid. Only the animation was nice.

I'm sure people who didn't play back then or don't agree are going to call this nostalgia again because we can't like something that's old and outdated .

Depends on the class. Vanilla and TBC had the most iconic sets, but they didn't have to try and look different from older sets because there weren't any. I am a fan of some recent sets, but usually only 1-2 sets per tier, and usually from classes I don't play
